How to Ajax-validate CheckBoxMultipleChoice?

[David Chang]

Hi, I am unable to addres this need and have to ask the group.

I am using the ajax approach to validate each field on a form. See the 
following:





If the above field gets focus and loses the focus without any value in it, 
there will be a red box around the input field. If it gets a value and loses 
its mouse focus, the red box disappears. All this happens without the user 
submitting the form.

The backend code is similar to the following:

...
inputComponent.add(new AjaxFormComponentUpdatingBehavior("onblur") {

@Override
protected void onUpdate(AjaxRequestTarget target) {
if (target != null) {
//add border and feedback panel here
}
}

@Override
protected void onError(AjaxRequestTarget target, RuntimeException e) {
if (target != null) {
//add border and feedback panel here
}
}); 


This approach works well for TextFields. 

Now I have a list of check boxes (implemented via CheckBoxMultipleChoice). At 
least one of them must be checked. The above Ajax approach is NOT working.

Can anybody there help me out on this?

All the best.

Re: Panel re-rendered twice, when the data is pulled in.

[Edward Zarecor]

Hmm, I took a working example that replaces a panel using an AJAX link
and altered the HTML to match what you have and, hey presto, after
clicking the link I have two versions of the panel content.  Reload
and I have one again.

I don't have the code in front of me, but I'll take a look again
tomorrow at what precisely is happening.

You should look at the HTML after the AJAX link has been clicked to
try to determine what is happening to the DOM.

In any event, I think "table fragment" as panel is a bad idea.

Re: Panel re-rendered twice, when the data is pulled in.

[jammyjohn]

Ed,

Thanks for your reply. I already tried this. But still the problem exists.
:(

setResponsePage(getPage(this)) seems to be the work around for this issue.
But the problem is, the other inputfields that have values on this page are
lost when the panel is re-rendered.

I am not sure how to solve this issue. 

Thanks
J.

I believe the cause -- and I've reproduced locally -- is this HTML:

Panel re-rendered twice, when the data is pulled in.

[jammyjohn]

Hi,

The page loads address panel with couple of text fields . When the search is
made for a particular address id, the address panel is rendered twice (one
panel with the data, the second panel without the data). Not sure  how to
avoid re-rendering of panel twice, 

setResponsePage(getPage()) can be a solution, but I dont want the whole page
to be refreshed as I am using 4 panels in my page.

The code is as below. Not sure if there is a problem in the way the markup
is structured.  Appreciate your help in this regard. 

/AddressPanel.html***/

/AddressPanel.java***/

public class AddressPanel extends Panel {   

public AddressPanel(String id, IModel model) {
super(id); 
  
   setDefaultModel(new CompoundPropertyModel(model));   
  
add(new RequiredTextField("address"));
add(new
TextField("address2").setConvertEmptyInputStringToNull(false));   
}   

}

/* java file that instantiates the panel */

final  Panel shipAddressPanel = new AddressPanel("shipperAddressPanel", new
Model(address.getShipAddress()));
shipAddressPanel.setOutputMarkupId(true);   
mawbForm.add(shipAddressPanel);   

add(mawbForm);

final TextField shipIdTf =  new TextField("shipperId", new
PropertyModel(dtomodel, "shipperId"));  
shipIdTf.setOutputMarkupId(true);
mawbForm.add(shipIdTf);


shipIdTf.add(new AjaxFormComponentUpdatingBehavior("onBlur"){   

private static final long serialVersionUID = 1L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
Shipper shipper=
shipDao.loadShipAddress(Long.parseLong(shipIdTf.getDefaultModelObjectAsString()))
   
Address address = new Address();
address.setShipAddress(shipper);

shipAddressPanel.setDefaultModelObject(address.getShipAddress());
target.addComponent(shipAddressPanel);
}

});

Re: urlFor not performing an accurate url

[Jeremy Thomerson]

your page is probably mounted with the default mounting strategy, which uses
the "seo-friendly" folder style parameters.  instead, you should mount that
page with the QueryStringUrlCodingStrategy

urlFor not performing an accurate url

[Fernando Wermus]

Hi all,
I need a url similar to the following example

www.example/test?url=map/myMap.swf

But urlFor constructs the followng

www.example/text/url/map/myMap.swf/

The last slash makes that the swf will not be correctly added.

Why RequestCycle.get().urlFor is not doing what I do expect?

Instead, I had to construct it by hand.

thanks in advance

Re: Get data from main application

[d2marcelo]

That's correct. 

APP 1 will call APP2 and pass the string  like "ABCDEFG"  in the url.. 
I was just thinking if this is the best way to do it. 

Thanks

Re: Get data from main application

[Jeremy Thomerson]

Depends on what your String is.  Do you mean that you need to redirect a
user from app one to app two, and you could pass this string in the URL (as
a query parameter)?  If s, just create a wicket bookmarkable page and use
the PageParameters to get the string.

Re: Get data from main application

I'm open to suggestions on this.  What is a simple way to send the string . 
This is coming from a webapp written in a diff java framework. jsf

Possibility a simple get to the url with the string or use RESTfull service.
Trying to be away from database option.  I'm not familiar with jmx. 

Anyway, any suggestion would be good to get me started.

Thanks,

Marcelo

How are you sending the string?  As a query string parameter, a JMS message,
something in the database?

Re: Markup Inheritance example with Ajax?

[Jeremy Thomerson]

If you want to do this, you are basically using the single-page paradigm
where your content is always a panel.  Basically you just create a single
page, and then all of your content goes into panels instead of pages with
markup inheritance.  Then swap the panel in your link and add it to the ajax
response.  You can make these bookmarkable through PageParameters.

Wicket: On RadioChoice component, invoke form submit, what am I missing

[Brown, Berlin [GCG-PFS]]

There are some components in wicket that seem to be associated with a
form, but I can't get them to actually submit the form.
 
Or at least, I can't get them to submit the form, if I have a hierarchy
of FORM -> PANEL -> COMPONENT/RADIOCHOICE
 
For example, I can create a "submitlink" or button and those components
submit:
 
return new SubmitLink(id, form) {   
   @Override
   public void onSubmit() {
this.setResponsePage(pageClass);
   }
  };
 
That works above.
 
I want to be able to perform a submit on a radio choice, on change. E.g.
 
new OnChangeHandler() { 
 
 @Override
 public void onChange(final Object sel) {  
  // On submission, submit back to form
  setResponsePage(Page.class);
 } 
 
// MY CONTAINER IS NOT A FORM BUT A CHILD OF A FORM (E.g. FORM -> PANEL
-> RADIOCHOICE
 
public RadioChoice addRadioGroup(final WebMarkupContainer container,
final Object modelObject, 
   final String groupName, final String propFieldName, final String []
optionsArr, final OnChangeHandler handler) {
 
  final RadioChoice radioGroupYesNo = new RadioChoice(groupName, new
PropertyModel(modelObject, propFieldName), Arrays.asList(optionsArr)) {
 
 @Override
   public boolean wantOnSelectionChangedNotifications() {   
return (handler != null); /* When the handler is not null, enable on
change */
   }
   @Override
   public void onSelectionChanged(Object newSel) {
if (handler != null) { 
 handler.onChange(newSel);
} else {
 super.onSelectionChanged(newSel);
}
   }   
  };
  container.add(radioGroupYesNo);
  return radioGroupYesNo;
 }
 
With the code shown above, the page refreshes, but I want to submit the
form and do a page refresh.
 
I don't see where I could associate the form with the RadioChoice?

Does RadioChoice need to imlement IFormSubmittingComponent?

Re: Submitting a component value on a ajax call of a different component

[jammyjohn]

Thank you so much for your reply. I tried using getCallbackScript on my
dropdown box. But it is never been called and also the fetch value on the
wicket side returns null for the dropdown box.
Not sure where I am doing wrong. Please suggest.
 
My code is as below..
/DropdownChoice**/
final DropDownChoice typeOption=new DropDownChoice("type",
list){  
private static final long serialVersionUID = 1L;
@Override
protected CharSequence getDefaultChoice(Object 
selected) {
return "--";
}
 protected boolean 
wantOnSelectionChangedNotifications() {
return true;
}
};  


/*adding to the form and setting outputmarkupid to true
form.add(typeOption.setRequired(true).setOutputMarkupId(true)); 

/adding AbstractDefaultAjaxBehavior to the above dropdownchoice /

typeOption.add(new AbstractDefaultAjaxBehavior() {  

private static final long serialVersionUID = 1L;
@Override
protected void respond(AjaxRequestTarget target) {
// TODO Auto-generated method stub
System.out.println("this is not getting 
printed");

}
@Override
protected CharSequence getCallbackScript(boolean 
onlyTargetActivePage)
 {
System.out.println("not getting printed");
 return generateCallbackScript("wicketAjaxGet('" +
getCallbackUrl(onlyTargetActivePage) +

"&mawbTypeDataOptionValue='+$Wicket.$("+mawbTypeDataOption.getMarkupId()+").value"
+
 ");");
 }


});



 final TextField nameTf = new TextField("name");   
   
form.add(nameTf.setConvertEmptyInputStringToNull(false).setOutputMarkupId(true));

//**trying to access ddc value from onBlur of the
textfield**/
 nameTf.add(new AjaxEventBehavior("onBlur") {
private static final long serialVersionUID = 1L;
@Override
protected void onEvent(AjaxRequestTarget target) {
nameTf.setModelObject("");  


Request request = 
RequestCycle.get().getRequest();
 String ddcValue = request.getParameter 
("mawbTypeDataOptionValue");
 System.out.println("this always prints null 
"++ddcValue);  

nameTf .modelChanged();

   target.addComponent(nameTf);

  target.addComponent(feedbackPanel);
}

});

Re: Markup Inheritance example with Ajax?

[Edward Zarecor]

What you are trying to accomplish doesn't require markup inheritance.

You can use a panel and replace it with an Ajax link.

That panel could be nested within wicket children participating in
markup inheritance, but that's another matter.  The panel should be
the component added to the AjaxRequestTarget.

Ed.

Markup Inheritance example with Ajax?

[heapifyman]

Hello all,

I would like to extend the Markup Inheritance example
(http://wicket.apache.org/examplemarkupinheritance.html) by replacing
the content part of the page (i.e. the wicket:child) using Ajax.

I tried to replace the BookmarkablePageLink on the BasePage with an
AjaxLink but this does not seem to work because one cannot add a WebPage
(e.g. Page1 in the example) to the target in the onClick() method.

Is there a way in Wicket to have a BasePage with header, content and
footer and replace the content by using Ajax?

I'd appreciate if anyone could point me to some example or documentation.

Best regards,
philip

Why do you see the need for documentation specific to generics in 
Wicket? Once you understand Java generics, their usage in Wicket is 
straightforward. Consult the Javadocs, and even that is often 
unnecessary---for an IModel, T must be the type of the model object, 
for instance.


Please ask some more specific questions if you have any.

Cheers,

Re: Listview and hibernate question: Objects don't get deleted before the listview getObject() is called

[James Carman]

Looks like if you use Spring 3.x, you can do it.  You have to use the
"value" of the @Transactional annotation to figure out which tx
manager to use.

Re: Listview and hibernate question: Objects don't get deleted before the listview getObject() is called

[pieter claassen]

Yes, I reload the objects using my DAOs but, I have 2 MySQL databases on the
backend and so far have not been using @Transactional. This might be the
problem.

Now I just have to figure out to configurefor more than one transaction manager and
make sure the different DOAs use the right txManager.

 It seems that ListView renders the new view before the transaction is

 Any ideas?

Docu/Examples of Models and Generics in Wicket 1.4?

[Alessandro Bottoni]

Hi All,
I'm new to Wicket and I'm studying it with "Wicket in Action". As you
surely know, this book is based on Wicket 1.3, that does NOT use
generics, while the current version is 1.4 and DOES use them (as will do
the next ones).

Put aside this page:

https://cwiki.apache.org/WICKET/migrating-to-wicket-14.html#MigratingtoWicket1.4-Modelchanges

I was unable to find any other documentation and/or example  regarding
the use of Java Generics with Wicket 1.4. (Actually, there is also this
historically-interesting report of the discussion about generics:
https://cwiki.apache.org/WICKET/generics.html).

Does anybody know of any other documentation or example I can/should use
as a reference while studying this part of Wicket 1.4?

Thanks in advance.

I find that when I delete objects from my ListView, my model object for the
ListView still contains a reference to the object. When the view tries to
render, the object is already removed from the database and I get a null
response on my hibernate load(). I use opensessioninview and when I check my
logs, the delete statement comes way after the view was rendered.

It seems that ListView renders the new view before the transaction is closed
(but even then, the delete should be visible to later sql in the same
transaction).

Any ideas?
Regards,
Pieter

public Object getObject() {
return getDocumentList();
}

setMarkupId() needs to be combined with setOutputMarkupId(true);

For some reason the first method worked fine but the second method
didn't.

Re: Session.replaceSession() behavior

[Matthias Keller]

Hi Doug

As described in the javadoc, the replaceSession() only replaces the 
(underlying) HTTP Session to help against session fixation attacks.
What is your goal exactly? If the user logs in and still has an earlier 
session, that that one will be destroyed?
In that case consider to use  session.invalidateNow()  to immediately 
destroy the (old) session and then create a new one.
Notice: When using invalidateNow() and creating a new one, the static 
method  Session.get() will still get you the previous (destroyed) 
session while being in the same call...

I am seeing a new HttpServletSession being created but not my wicket application session. 
 I have placed a System.out.println( "new AppSession()..." ) in the constructor 
and I am not seeing that.

Can anyone confirm this behavior as well?  Is this a bug?  Is there a work 
around?

I am using Wicket 1.4.9

BTW...my use case is someone goes to the LoginPage and logs in, the previous 
session will be cleared.

Multi-window support is also on (however...changing this doesn't affect the 
outcome)

Thanks

Howto get TagTester for childs of components in ajax response?

[Per Newgro]

Hi *,

I would like to test the markup of my (Ajax-)updated component. Until now i 
simply used String.contains(String). But this is very fragile on markup 
manipulation in my code.

So i would like to get the tags inside the ajax-response CData section and 
simply extract everything (analogous to TagTester / WicketTester).

is someone out there providing already a solution for this? Maybe i missed a 
blog or something.

In addition here a little example of what i try to achieve
>From code below i would like to test if attribute style on component 
>"brdPage_frmArrangementType_lvArrangementTypes_1_description" is set to 
>"border: 2px solid red;"

Docu/Examples of Models and Generics in Wicket 1.4?

[Alessandro Bottoni]

Hi All,
I'm new to Wicket and I'm studying it using "Wicket in Action". As you
surely know, this book is based on Wicket 1.3, that does NOT use
generics, while the current version is 1.4 and DOES use them (as will do
the next ones).

Put aside this page:

https://cwiki.apache.org/WICKET/migrating-to-wicket-14.html#MigratingtoWicket1.4-Modelchanges

I was unable to find any other documentation and/or example  regarding
the use of Java Generics with Wicket 1.4. (Actually, there is also this
historically-interesting report of the discussion about generics:
https://cwiki.apache.org/WICKET/generics.html).

Does anybody know of any other documentation or example I can/should use
as a reference while studying this part of Wicket 1.4?

Thanks in advance.
